Enjambment
Enjambment - The continuation of the sense and therefore the grammatical construction beyond the end of a line of verse or the end of a couplet.

Example 1-
An example of enjambment is in the poem “A Considerable Speck” by Robert Frost in lines 24, 25 and 26: “I have none of the tenderer-than-thou / Collectivistic regimenting love / With which the modern world is being swept”.

Effect 1-
The use of enjambment here creates an effect of natural speech. Because speech is not orderly and definite, enjambment here allows for smooth and speech-style sounding poetry.

Example 2 –
Another example of enjambment can be seen in lines 89 to 94 of Act 4 Scene 2 : “A servant that he bred, thrilled with remorse, / Opposed against the act, bending his sword / To his great master, who, <thereat> enraged, / Flew on him and amongst them felled him dead, / But not without that harmful stroke which since / Hath plucked him after.”

Effect 2-
The effect of using enjambment at this section is to imply a build up or a series of tense situations, building up suspense and anxiety. This, characteristic and reflective of the scene considering it is one filled with action.
